Still randomly disconnects and requires password to be retyped in, or randomly get proxy errors and have to restart.

PIA performs flawlessly. Even though the app warns of a bit of performance hit while using it, I normally see a performance increase. I have pulled down gigabytes of data through both the Firefox addon and the Linux system level VPN. No problems, ever.

Ok, but could be better.

perfect safe

Unbelievable! Permanent logouts on different devices, connection drops several times a day. When will this finally be fixed?

It would be great if it has a whitelist function or the exclusion list accepts regular expressions.

Constant disconnects and authentication errors

Frequent connection drops that force me to change servers. It says it's still connected but I can't open a single website unless I swap servers. Also occasionally it just logs me off and asks for credentials or I get pop up window to provide those when it attempts to connect to VPN server. I can't just log out and stay logged out, because after restarting the browser it logs me back in. I had to reinstall the addon to temporarily solve some of those issues. Can't depend on it because of the frequency of the issues and how long it takes to resolve those.

l'addon à cesser de fonctionner depuis plus de 1 mois, j'ai attendu que le bug soit corriger mais vus que pia ce bouger pas j'ai finalement contacter le support, et comme d'hab il te sorte les mêmes réponse, changer de server, deconnecté reconnecter vous, d'installer re installer l'addon etc mais comme le soucis viens de leurs addon forcément ces solution son bidon, au final il on cloturé mon ticket = ) des que mon abonnement et fini je me casse voir ailleurs, après 10+ ans chez eux, le temps et venu d'aller voir ailleurs.

Getting the same errors as @Cynitec below.

This add-on needs to be updated, big time!

The last update was (as of today) 7 months ago, so I think this is the problem.

I may have to cancel this if they can't get a newer version released.

Almost useless. I regularly have to switch server because the connection just stops working, and now I'm getting the error "The proxy moz-proxy://https-us-washingtondc.privateinternetaccess.com:80 is requesting a username and password. The site says: “Private Internet Access”"

I'll be switching VPN providers when my subscription ends

Update: 8 months later I'm still having to switch servers, and reinstall the add-on every week or so.

Enabling Fingerprint Protection prevents Firefox from opening windows maximized.

I have been using Private Internet Access for 4 months and have their add-on/extension installed in Firefox, Chrome and Vivaldi on multiple desktops, laptops and virtual machines (Linux and Windows). Not sure what issues other users, who complain and give 1 star, have in their specific environments, but for me the PIA VPN service always was and continues to be reliable, and all their add-ons work flawlessly. Sometimes, when not using the browser for a while, the connection may drop. Not a big thing - just disconnect and reconnect again. Very happy with PIA so far and would recommend. 5 stars from me!

No longer works correctly, keeps dropping connection to the internet.
